SOIL : Dig Anywhere

Winner of the Excellence Award in the Education & Kids Category
Best App Award 2024 Dig freely into the ground and explore what lies beneath the soil! “Soil” is a remake based on scenes and landscapes from Let’s Explore Inside the Earth, a representative work by the Japanese picture book author Satoshi Kako, first published in 1975.
With “soil” as its main theme, this work has been newly reimagined with original illustrations created by designer Tsutomu Kakinuma. From the time we are very young, we naturally know that soil exists.
But what exactly is soil? How is it formed? And how does it affect our lives and the lives of other living things?
Perhaps there are not many adults who can explain these things in detail. In this work, you can learn about soil — something that exists almost everywhere around us, yet is often overlooked because it seems so ordinary.
You can also discover many different things connected to soil, such as living creatures, natural phenomena, human production activities, and culture. This work is filled with answers to countless questions — hundreds, even thousands of them.
However, this work is still only a “created world” inside software. The number of living creatures and natural phenomena it can show is far smaller than those found in real nature. So after enjoying this app, we hope you will go outside, look closely at real nature with your own eyes, and feel the difference between the “created world” and the real one. Please note that some small animals and other elements are shown larger than their actual scale, because they would be difficult to see if displayed at their true size.
